Problems solved by technology

[0002] At present, many rivers and lakes are eutrophic, the water quality is deteriorating, and water environmental problems are getting more and more attention. Using a single decentralized treatment technology, it is difficult for the effluent to meet the "Environmental Quality Standards for Surface Water" (GB3838-2002) and "Urban Sewage Reuse Landscape Environmental Water Quality" (GB / T18921-2002); at the same time, different sewage decentralized treatment technologies have their own advantages, disadvantages and scope of application, which limits the application scope and effect of decentralized treatment techniques

Embodiment 1

[0041] Embodiment 1: Ecological combined floating bed

[0042] Such as figure 1 As shown, an ecological combined floating bed is a device for repairing polluted water bodies. The three-dimensional ecological floating bed is divided into two layers, I and II, and the first layer is a layer of aquatic plants. This layer is spliced ​​by nine 333mm*333mm cube floating beds. Composed of boards, each splicing board contains a planting basket with a diameter of 170mm, each planting basket is planted with water spinach and reeds, the innermost layer of the planting basket is nutrient soil, the outermost layer is loofah straw, and the plastic between the two layers The frames are separated, and each cube splicing plate is connected with a connection port. The second layer is the advanced treatment layer: this layer is divided into A, B, and C treatment areas, mainly composed of zeolite-loaded nano-TiO 2 Composition, zeolite-loaded nano-TiO 2 The suspension support A is connected to t...

Embodiment 2

[0046] Embodiment 2 ecological combination floating bed

[0047] It is basically the same as Example 1, except that the aquatic plant is cress.

Embodiment 3

[0048] Embodiment 3 Energy-saving ecological resource recovery type ecological restoration integrated system

[0049] The integrated system includes a plurality of ecological combined floating beds in Embodiment 1 or 2, a plurality of multifunctional ecological bags, and a plurality of micro-nano aeration devices coupled. An ecological combination floating bed is set every 25m, and a micro-nano aeration device is set every 10 floating beds. The multi-functional ecological bag includes a denitrification ecological bag, a phosphorus removal ecological bag and an organic matter removal ecological bag. The three kinds of bags are staggered. Stacked at the junction of the water and the shore, the ecological bag is fixed with wooden stakes near the water side, and the grass is planted near the shore to buffer the impact of the shore sewage on the ecological bag. The multi-functional ecological bag is laid layer by layer in the way of shunting. After the lower bag body is laid, a pyr...

Abstract

The invention discloses an ecological combination floating bed. An ecological floating bed is divided into an upper aquatic plant layer and a lower deep treatment layer; the aquatic plant layer is composed of a plurality of floating bed splicing plates, a planting basket is installed on each floating bed splicing plate, aquatic plants are planted in the planting baskets, the deep treatment layer is divided into a treatment zone A, a treatment zone B and a treatment zone C from outside to inside, the treatment zone A is mainly composed of zeolite loaded nano-TiO2, the treatment area B is mainly composed of an aquatic animal cage, the treatment zone C is mainly composed of an artificial medium, the floating bed is fixed by four fixing rods, and the periphery of the floating bed is made up of a fishing net. The invention also discloses an energy-saving ecological resource recycling type ecological restoration integrated system and application thereof. Three recovery technologies of micro-nano aeration, a multi-functional ecological bag and the three-dimensional partition combined ecological floating bed are combined to not only realize the removal of pollutants of water per se, but also control a bunding source and intercept pollution from the bunding source, and cause interception to bank pollutants, so as to achieve the effect of integrated ecological restoration of bank and water.

Description

technical field [0001] The invention belongs to the technical field of water quality purification for ecological restoration of polluted water bodies, and specifically relates to an energy-saving ecological resource recovery type ecological restoration integrated system and its application. Using and other aspects to comprehensively consider the complete set of technologies for ecological restoration of water systems, to form an integrated technology for ecological restoration of rural rivers with high efficiency, energy saving and environmental friendliness. Background technique [0002] At present, many rivers and lakes are eutrophic, the water quality is deteriorating, and water environmental problems are getting more and more attention. Using a single decentralized treatment technology, it is difficult for the effluent to meet the "Environmental Quality Standards for Surface Water" (GB3838-2002) and "Urban Sewage Reuse "Water Quality for Landscape Environment" (GB / T18921...
